To find the reset function on your Viessmann boiler, look right on the control panel, where it’s typically a dedicated button or a combination of keys for quick access. In my years installing these reliable units across UK homes,
I’ve noticed that on popular models like the Vitodens 100-W, the reset is often marked with a circular arrow icon near the digital display. For touchscreen versions in modern properties, it’s an on-screen prompt, while older dial-based systems might require holding ‘Mode’ and ‘OK’ simultaneously.

How to Reset a Viessmann Boiler: Step-by-Step Instructions
The step-by-step instructions for resetting a Viessmann boiler start with identifying and fixing the underlying fault to ensure a successful reboot. As someone who’s reset hundreds of these efficient German boilers in UK settings, I always advise starting safely: Once the fault has been addressed, you’ll need to follow the proper procedure to reset the boiler.
This includes understanding how to repressurise a Viessmann boiler, which involves adding water to the system until it reaches the recommended pressure level. Always ensure that you check the pressure gauge and any relevant indicators before restarting the unit.
Additionally, it’s important to familiarise yourself with common error codes that may arise during operation. In particular, the viessmann f5 fault code explained can provide valuable insights into specific issues that might require attention before performing a reset.
Always consult the manufacturer’s guidelines for detailed troubleshooting information for these error codes.
- Switch off the unit at the mains if needed, then check the error code on the display.
For most models, press and hold the reset button—often labelled or icon-based—for 3 to 10 seconds until the system cycles. - Wait a few minutes for the self-check; if it’s a gas condensing boiler like the Vitodens, listen for the fan to kick in.
Unique tip from my fieldwork: in hard water areas common in the UK, descale connections beforehand to prevent pressure-related lockouts recurring in your home heating network.
Resetting Specific Viessmann Models
For the Vitodens 050 or 100 series, hold the reset for about 5 seconds after clearing any blockages. On the Vitodens 200-W, use the touchscreen to navigate to the fault menu and select reset. If you have an older model, turning the mode dial while pressing OK often does the trick.
Safety Checks Before Resetting
Before any Viessmann boiler reboot, verify gas or oil supply and ensure no leaks—crucial for UK safety standards. Top up pressure if low, and bleed radiators to release trapped air in your central heating loop.
When Should You Avoid Resetting Your Viessmann Boiler Myself?
You should avoid resetting your Viessmann boiler yourself if the fault persists after one attempt or involves complex issues like electrical faults. In my expert opinion, drawn from troubleshooting countless UK home heating systems, repeated resets on a malfunctioning unit can mask serious problems such as a faulty PCB or blocked condensate pipe, leading to bigger repair bills for homeowners.
Landlords, especially, should err on caution for tenant safety— if smells of gas or unusual noises accompany the error, skip the DIY reboot and contact a Gas Safe engineer immediately to comply with UK regulations and protect your property’s heating infrastructure.
What Should You Do If Resetting Your Viessmann Boiler Doesn’t Fix the Issue?
If resetting your Viessmann boiler doesn’t fix the issue, the next step is to call a qualified engineer for a deeper diagnosis. From my extensive time in the field, I’ve learned that persistent errors in these advanced heating appliances often stem from worn parts like the diverter valve in combi setups or thermostat failures in system boilers. Additionally, it is crucial to be aware of Viessmann boiler common issues that can arise over time, such as buildup in the heat exchanger or issues with the pressure relief valve. Addressing these problems early can prevent further complications and ensure the longevity of your heating system. Regular maintenance checks can also help identify potential failures before they affect performance.
For UK homeowners facing cold spells, document the fault code and symptoms to speed up the fix; landlords can use this to claim on warranties. Meanwhile, consider temporary alternatives like electric heaters, but don’t delay—ongoing Viessmann heating glitches could indicate it’s time for an upgrade to maintain efficient warmth in your home.
